Executing Lisp Expressions
Emacs has several different major modes for Lisp and Scheme. They
are the same in terms of editing commands, but differ in the commands
for executing Lisp expressions.
The mode for editing source files of programs to run in Emacs Lisp.
This mode defines `C-M-x' to evaluate the current defun. *Note
Lisp Interaction mode
The mode for an interactive session with Emacs Lisp. It defines
LFD to evaluate the sexp before point and insert its value in the
buffer. Note: Lisp Interaction.
The mode for editing source files of programs that run in Lisps
other than Emacs Lisp. This mode defines `C-M-x' to send the
current defun to an inferior Lisp process. Note: External Lisp.
Inferior Lisp mode
The mode for an interactive session with an inferior Lisp process.
This mode combines the special features of Lisp mode and Shell mode
(Note: Shell Mode.).
Like Lisp mode but for Scheme programs.
Inferior Scheme mode
The mode for an interactive session with an inferior Scheme
These subnodes of the chapter on editing programs describe the editing
commands for working with Lisp programs, which are in fact available
- Expressions with balanced parentheses.
- List Commands
- The commands for working with list and sexps.
- Each program is made up of separate functions.
There are editing commands to operate on them.
- Program Indent
- Adjusting indentation to show the nesting.
- Insertion of a close-delimiter flashes matching open.
- Inserting, killing, and aligning comments.
